An electric stabiliser (1) for stabilising a floating structure is described. The electric stabiliser (1) includes a track (2) for guiding a mover (6) as a moving stabiliser mass. A direct current (DC) linear motor (8) includes a planar stator (10) that extends along the track (2) and the mover (6) that is adapted to move forwards and backwards along the track (2) as the stabiliser mass. The planar stator (10) includes a polyphase stator winding (16) with a plurality of winding coils (14) connected to define a plurality of phase windings. The mover (6) includes a plurality of permanent motor magnets (40) facing the polyphase stator winding (16) that define a plurality of mover poles of alternating polarity (i.e., north and south polarity) along the track direction. Two active magnetic bearings (44, 48) is positioned between the track and a main body (32) of the mover (6) for selectively levitating the mover. In use, the active magnetic bearings (44, 48) levitate the mover (6) above the track and the DC linear motor (8) is controlled to move the mover (6) backwards and forwards along the track (2) to dampen a rolling or pitching movement of the floating structure, for example.
